Description
Loud and Deep Rumble. Match your 5.3L GMC Sierra’s bold exterior and impressive performance with a deep and loud performance exhaust sound by upgrading to the Dynomax Ultra Flo Welded Dual Rear Exit Exhaust System with Polished Tips. This cat-back exhaust is equipped with the Continuous Roving Fiberglass (CRF) Technology that eliminates the unwanted interior resonance for a bolder exhaust tone.
Superior Engine Boost. The single-in, dual-out high-flow muffler design and mandrel-bent tubing free up your engine’s power by allowing faster and more efficient flow of the exhaust gases. The smooth path without the restrictive angles and bends facilitates more power generation. You can also experience improved fuel economy alongside the enhanced performance.
Premium Construction. Engineered using ultra-smooth mandrel-bent, 3-inch and 2.50-inch stainless steel tubes, this Ultra Flo Welded Exhaust System is a superb, long-lasting upgrade. The stainless steel construction withstands the highly corrosive exhaust chemicals and the extreme temperatures caused by the intense catalytic activities. Moreover, it is fully welded that offers extra durability and the band clamps with 360-degree seals eliminate leak paths. Additionally, the stylish, 3-inch, slant-cut, polished exhaust tips bring some captivating details to your truck’s aggressive stance.
Straightforward Installation. This Ultra Flo Welded Dual Exhaust System is intended for a bolt-on installation. It is seamlessly compatible with your vehicle’s factory mounting points and can be installed using basic hand tools with light to moderate mechanical skills.
